Title: Improvements in or relating to an Electronic Numerical Dividing Apparatus
IPC: G06F7/62
Filed: 1967-10-17
Abstract: 1169769 Electrical dividing apparatus COMMISSARIAT A L'ENERGIE ATOMIQUE 17 Oct 19 [18 Oct 1966] 47323/67 Headings G4D D7X D6Y D6C1 and D6C2  A value y is divided by a value x/k by registering x/k in a memory and feeding y into a counter which resets each time a coincidence gate operates, the number of said operations being registered in another counter. As applied to indicating how the power of a nuclear reactor varies, the pulses detected from the reactor in the preceding period (of say 10 seconds) are shifted from counter 1 by clock 21 to a memory 10a, divided by a power of 10 and moved to memory 10b. The pulses in the ensuing period are fed to counters I and 3, the attainment of the number in 10b stepping on a further counter 14 and resetting 3. At the end of the period the clock 21 shifts the number in 14 to a memory 19 and display 20. Allowing for the factor k the display 20 shows whether or not the power has increased or decreased. This is also indicated by the count in 14 reaching or not a terminal connecting to a sign circuit 7 so that + or - is indicated at 25. In the case of a decrease circuit 7 operates a complementing circuit 23 so that the display 20 is properly negative.

Abstract: 490,610. Electromagnetic switches. ROBERTSON, G., and ROCHER, E. J. Feb. 20,1937, No. 5168. [Class 38 (v)] [Also in Groups XXVII and XXXV] A battery isolating switch which opens automatically after a time interval commencing with the stoppage of an internalcombustion engine is held closed both by generator current and by a pressure change consequent on the running of the engine. Contacts 3, 4 are spanned by a laminated bridge 5 mounted on a stem 6 to which is secured a sleeve 12 of magnetic material and a diaphragm 17. A coil 9 surrounds the sleeve 12, and the diaphragm is clamped at the rim forming compartments 21, 23, the space 21 being open to the atmosphere and the space 23 to engine suction by way of a pipe 24, with a ball-valve 26 to prevent damage due to back-firing.

[Also in Division H3] In the electro-erosion of a workpiece P by an electrode E, fed with voltage pulses through a control means A, the latter is controlled to produce a succession of trains of pulses separated by pulse-free intervals. Control means A may be a battery of semi-conductors which are triggered by a transistor T 1  to transmit a voltage pulse from source S 1  to the erosion gap. The base of T 1  is fed with rectangular pulses, Fig. 2a (not shown), from output 1 of oscillator B. Output 2 of the oscillator has a saw-tooth voltage, Fig. 2b (not shown), appliep to an astable or monostable low frequency multivibrator consisting of transistors T 2 , T 3 . The output is applied to base of transistor T 4  whose collector is connected through R 9  to the base of T 1 . When T 4  is conductive, T 1  becomes conductive and during this period the rectangular pulses from oscillator B are inoperative and cause the pulse-free intervals. Fig. 2f (not shown). In another embodiment, Fig. 3 (not shown), the invention is applied to the apparatus described in Specification 1,074,139 which produces discharges of constant duration, Fig. 4b (not shown). In this embodiment, the discharge pulses are produced by a switching device A controlled by a Schmidt trigger 3 and two monostable multivibrators 4, 5. An astable or monostable multivibrator 8 and a flip-flop circuit 9 are used to impress further control on the monostable multivibrator 5 and so produce the pulse free intervals. During some or all of these intervals the electrode may be partially withdrawn, due to interruption of the gap voltage, to facilitate circulation of dielectric liquid through the erosion gap.

Dual circuits operate wheel cylinders 1, 1<SP>1</SP> and 1<SP>11</SP>, 1<SP>111</SP> via cut-off valves 9, 20. If a skid is imminent electromagnetically operated valves 11, 13 are respectively caused to open and close to allow pressure fluid to pass from an accumulator 12 to control chambers 10, 21, causing pistons 5, 21 to retract and close valves 9, 20 through hydraulic or mechanical connections, further retraction expanding the volume of the circuits to relieve braking pressure. Upon the wheels attaining a predetermined speed compared with that of the vehicle, the valves 11, 13 are respectively closed and opened and pistons 5, 16 return to their initial positions under the influence of springs 15 and fluid pressure. Fluid in chambers 10, 21 passes to a return line 14. If the accumulator pressure fails no pressure is supplied to the chambers 24 of the units so that on brake actuation valves 20 are closed so that wheel cylinders 1<SP>11</SP>, 1<SP>111</SP> are not actuated. Thereafter only cylinders 1, 1<SP>1</SP> are pressurized. The invention may be applied to various arrangements, e.g. duplicated front brakes or diagonal pair arrangements.
